Title: Stress-induced nematicity in ${EuFe}_{2} {As}_{2}$ studied by Raman spectroscopy

Abstract

Here, we use polarized Raman scattering to study the structural phase transition in EuFe ₂ As ₂, the parent compound of the 122-ferropnictide superconductors. The in-plane lattice anisotropy is characterized by measurements of the side surface with different strains induced by different preparation methods. We also show that while a fine surface polishing leaves the samples free of residual internal strain, in which case the onset of the C₄ symmetry breaking is observed at the nominal structural phase transition temperature T _S , cutting the side surface induces a permanent fourfold rotational symmetry breaking spanning tens of degrees above T _S .

Intertwined Magnetic and Nematic Orders in Semiconducting ${KFe}_{0.8} {Ag}_{1.2} {Te}_{2}$

Journal Article Song, Yu ; Cao, Huibo ; Chakoumakos, B. C. ; ... - Physical Review Letters

Superconductivity in the iron pnictides emerges from metallic parent compounds exhibiting intertwined stripe-type magnetic order and nematic order, with itinerant electrons suggested to be essential for both. Here we use x-ray and neutron scattering to show that a similar intertwined state is realized in semiconducting KFe_0.8Ag_1.2Te₂ (K₅Fe₄Ag₆Te₁₀) without itinerant electrons. We find that Fe atoms in KFe_0.8Ag_1.2Te₂ form isolated 2×2 blocks, separated by nonmagnetic Ag atoms. Long-range magnetic order sets in below T_N ≈ 35 K, with magnetic moments within the 2×2 Fe blocks ordering into the stripe-type configuration. A nematic order accompanies the magnetic transition, manifest as a structuralmore »« less

Journal Article Song, Yu ; Yuan, Dongsheng ; Lu, Xingye ; ... - Physical Review Letters

Spin nematics break spin-rotational symmetry while maintaining time-reversal symmetry, analogous to liquid crystal nematics that break spatial rotational symmetry while maintaining translational symmetry. Although several candidate spin nematics have been proposed, the identification and characterization of such a state remain challenging because the spin-nematic order parameter does not couple directly to experimental probes.more »« less

$X {Fe}_{4} {Ge}_{2} (X = Y, Lu)$ and ${Mn}_{3} Pt$ : Filling-enforced magnetic topological metals

Journal Article Wang, Di ; Tang, Feng ; Po, Hoi Chun ; ... - Physical Review B

Magnetism, coupled with nontrivial band topology, can bring about many interesting and exotic phenomena, so that magnetic topological materials have attracted persistent research interest. However, compared with nonmagnetic topological materials (TMs), the magnetic TMs are less studied, since their magnetic structures and topological phase transitions are usually complex and the first-principles predictions are usually sensitive on the effect of Coulomb interaction. Here we present a comprehensive investigation of XFe₄Ge₂ (X = Y, Lu) and Mn₃Pt, and find these materials to be filling-enforced magnetic topological metals. Our first-principles calculations show that XFe₄Ge₂ (X = Y, Lu) host Dirac points near the Fermi level at high symmetry point S. These Dirac points are protected bymore »« less

Persistent magnetism in silver-doped $BaF e_{2} A s_{2}$ crystals

Journal Article Li, Li ; Cao, Huibo ; Parker, David S. ; ... - Physical Review B

Here, we investigate the thermodynamic and transport properties of silver-substituted BaF e ₂ A s ₂ (122) crystals up to ~ 4.5 % . Similar to other transition-metal substitutions in 122, Ag diminishes the antiferromagnetic ( T _N ) and structural ( T S ) transition temperatures, but unlike other electron-doped 122s, T _N and T_S coincide without splitting. Though magnetism drops precipitously to T _N = 84 K at doping x = 0.029 , it only weakly changes above this x , settling at T _N = 80 K at x = 0.045 .

Nanocalorimetric evidence for nematic superconductivity in the doped topological insulator ${Sr}_{0.1} {Bi}_{2} {Se}_{3}$

Journal Article Willa, Kristin ; Willa, Roland ; Song, Kok Wee ; ... - Physical Review B

Spontaneous rotational-symmetry breaking in the superconducting state of doped Bi2Se3 has attracted significant attention as an indicator for topological superconductivity. In this paper, high-resolution calorimetry of the single-crystal Sr_0.1Bi₂Se₃ provides unequivocal evidence of a twofold rotational symmetry in the superconducting gap by a bulk thermodynamic probe, a fingerprint of nematic superconductivity. The extremely small specific heat anomaly resolved with our high-sensitivity technique is consistent with the material's low carrier concentration proving bulk superconductivity. The large basal-plane anisotropy of H-c(2) (Gamma(exp) = 3.5) is attributed to a nematic phase of a two-component topological gap structure eta = (eta(1), eta(2)) and causedmore »« less
